Mobile Software Engineer at Mosai in Jacksonville, Florida

Job description

• Mosai is seeking a mid-to-senior Mobile Software Engineer to build and evolve Mosai Mobile, the iOS and Android application clinicians use in the field. You will deliver reliable, intuitive features that help home-based care teams document care, coordinate work, and remain productive when connectivity is limited or unavailable.
• The ideal candidate is a strong React Native engineer who enjoys end-to-end ownership, collaborates effectively with Product and QA, and can contribute to native iOS and Android code when needed.

Responsibilities

• Help evolve an AI-native software development lifecycle by using AI-assisted tools for planning, implementation, testing, documentation, code review, and troubleshooting.
• Identify practical opportunities to improve development velocity and quality through AI-enabled workflows, while maintaining strong engineering judgment and appropriate human review.
• Design, build, test, and release features for Mosai Mobile using React Native, Expo, and TypeScript.
• Own work across the mobile client, including user interface, application state, API integrations, and local data storage.
• Build for reliability in real-world field conditions, including offline workflows, synchronization, error handling, retries, and app store releases.
• Contribute to native iOS and Android code when a feature requires platform-specific capabilities beyond JavaScript.
• Use AI coding assistants as part of the development workflow while maintaining responsibility for the quality, security, privacy, and correctness of released software.
• Write and maintain automated tests, participate in code reviews, and help improve engineering standards.
• Partner closely with Product, Design, QA, and backend engineering to deliver high-quality mobile experiences.
• Perform other duties as assigned.

Requirements

• Bachelor’s degree in Computer Science, Engineering, a related field, or equivalent practical experience.
• Demonstrated ability to use AI-assisted development tools effectively as part of the software development lifecycle, with accountability for code quality, security, privacy, and correctness.
• Five or more years of software engineering experience, including at least three years building and shipping React Native applications for both iOS and Android.
• Strong proficiency in TypeScript, JavaScript, React, and React Native.
• Experience integrating mobile applications with RESTful APIs.
• Ability to read, debug, and contribute to Swift and/or Kotlin code.
• Strong product judgment and the ability to translate user needs into clear, well-designed mobile experiences.
• Familiarity with AI-assisted development tools, such as Cursor, Codex, or Claude, and an interest in using them thoughtfully and effectively.
• Strong communication skills, sound judgment, and the ability to work independently in a collaborative environment.
• Experience helping teams adopt or improve AI-native engineering practices, including AI-assisted testing, code review, documentation, and developer workflows.
• Experience with Redux or comparable state-management solutions.
• Experience building offline-first mobile applications, including camera, image, and document-capture workflows.
• Experience with mobile CI/CD pipelines and releasing applications through the Apple App Store and Google Play.
• Experience in healthcare, health technology, or another regulated SaaS environment.
